ELECTRICAL INDICATING AND CUT-OUT APPARATUS FOR PORTABLE OR OTHERELECTRIC LAMPS.

SPECIFICATION forming part of Letters Patent No. 566,573, dated August25, 1896.

Application filed January 13,1896. Serial No. 575,227. (No model.)

To all) whom it may concern:

Be it known that we, ROBERT HAOKING and GEORGE BRAND, subjects of theQueen of Great Britain and Ireland, residing at Nottingham, England,have invented a new and useful Electrical Indicating and Out-OutApparatus for Portable and other Electric Lamps, of which the followingis a specification.

This invention relates to a convenient arrangement of portable electriclamp for cyclists, miners, and others provided with means for indicatingthe length of time during which the current has been used.

For the purposes of our invention we employ a clockwork ortime-indicator having a stop mechanism (which may be similar to that ofan ordinary stop-watch) so connected with the switch of the electriclamp that the manipulation of the switch to light the lamp sets theclockwork in operation, and the out ting out of the lamp simultaneouslystops the clockwork. Thus the indicator acts only at such times as thecurrent is flowing, and in order that our invention may be readilyunderstood we will describe the same with reference to the accompanyingdrawings, in which- Figure 1 shows a part-sectional elevation,

the balance-wheel e of the clock and stop its motion. The other end ofsaid lever is provided with a slot f, in which works a pin 9 on the endof a switch-lever h. We provide an aperture centrally in the base-boardto allow the finger to be inserted to conveniently operate the switch itand lever b.

In .the figures the switch-lever his shown over the contact-piece i, thecircuit through the lamp j being completed and the tooth d held off thebalance-wheel. On moving the switch-lever so that it rests against thestop 70 the circuit will be broken, and at the same time the tooth (1will be caused to bear upon the balance-wheel e and will so stop theclockwork. It will thus be apparent that the timeindicator will show onits dial the total time during which the current has been switched on,independent of interruptions, and hence if the user knows the totallength of time the battery was charged for he can readily tell at anymoment how much longer the charge still remaining in the battery willlast.

We claim as our invention The combination with a portable electric lampand the circuit connections, of a baseboard therefor having an openingin it and a timepiece supported by such base-board, a stop-lever withone end adjacent to the balance of the timepiece, a switch and circuitclosing contacts and a connection between the switch and the stop-leverat the aperture in the base, whereby access is given for moving theswitch and stop-lever to simultaneously turn off the current and stopthe time mechanism or the reverse, substantially as set forth.

In witness whereof we have hereunto signed our names in the presence oftwo subscribing witnesses.

ROBERT HAOKING. GEORGE BRAND.
